Macro tracy_client::register_demangler

macro_rules! register_demangler {
    () => { ... };
    ($path:path) => { ... };
}

Available on crate feature demangle only.

Registers a custom demangler function.

A default implementation for demangling Rust symbols can be registered by passing no arguments.

Custom implementations can be registered by passing a function with the following signature: fn(mangled: &str, buffer: &mut tracy_client::demangle::Buffer) -> std::fmt::Result

Custom demanglers:

• Must not write null bytes to the buffer.
• Returning Err or leaving the buffer unchanged will result in the symbol being displayed as-is.

See the module-level documentation for more information.

Examples

use tracy_client::{demangle, register_demangler};

// Register the default demangler.
register_demangler!();

// Register a noop demangler.
register_demangler!(demangle::noop);

// Register a custom demangler.
register_demangler!(my_demangler);

fn my_demangler(s: &str, buffer: &mut demangle::Buffer) -> std::fmt::Result {
    // Custom demangling logic...
    use std::fmt::Write;
    write!(buffer, "{s}")?;
    Ok(())
}
